Buttoned Tufted Kingfisher
Buttoned Tufted Kingfisher (#6BBF84) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (138°, 40%, 58%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.
Old French touffe, tuft. As a color modifier, tufted implies a hand-tufted-and-puffed quality, the visual register of Edwardian-and-Belle-Époque-tufted-upholstery hand-tufted-and-puffed-and-upholstered velvet-and-silk-and-leather tufted-and-puffed-upholstery surfaces under Edwardian-and-Belle-Époque hand-tufted-upholstery-and-cushion light. Sits at the modifier-and-texture end of the grid, parallel to fluff and flock in usage.
The family Alcedinidae — particularly Alcedo atthis, the European common kingfisher whose iridescent turquoise-blue plumage gives the color its name. The color refers to a male European kingfisher's wing: a saturated, slightly cool deep blue-green with the iridescent satin finish of structurally colored feathers.
